The top of the second shown groove lattice 4 and the space bar of the 3rd groove lattice 5 offers the second opening 8, to realize being communicated with of the second groove lattice 4 and the 3rd groove lattice 5.The lower end of the space bar of the 3rd groove lattice 5 and the 4th groove lattice 6 offers the 3rd opening 9, achieves being communicated with between the 3rd groove lattice 5 with the 4th groove lattice 6.Feed pipe 10 is arranged at the first opening 7 position, matrix to be clean to be injected the first groove lattice 3 and the second groove lattice 4 simultaneously; Discharge nozzle 11 is arranged at the middle and upper part of the 4th groove lattice 6, for matrix complete for reaction being discharged.
Shown aeroscopic plate 13 is arranged at the second opening 8 position obliquely, and aeroscopic plate 13 is positioned at the top of U-shaped pipe 12 gas outlet, realizes the guide functions to eluting gas from U-shaped pipe 12, to increase the stirring of the 3rd groove lattice 5 and the second groove lattice 4 mesostroma.The top that the first shown groove lattice 3 and the top of the second groove lattice 4 are respectively arranged with the first gas circulation port 15 and the second gas circulation port 16, second groove lattice 4 is provided with gas vent 14.
As the preferred concrete structure of one, the distance bottom the bottom distance purification tank of shown U-shaped pipe 12 is 1/4 of whole purification tank height, and the height of U-shaped pipe 12 is 1/3 ~ 1/2 of whole purification tank height, and the width of U-shaped pipe 12 is no more than the width of each groove lattice; The distance of two vertical tube distance dividing plates 2 of U-shaped pipe 12 is no more than 0.2m, and the internal diameter of U-shaped pipe 12 is no more than 0.05m.The angle of inclination of aeroscopic plate 13 is 30 ° ~ 45 °, and the length that aeroscopic plate 13 is arranged in the 3rd groove lattice 5 part is 1/2 of whole aeroscopic plate length.
The height of the height of the first opening 7 to be the height of the 1/8, second opening 8 of whole purification tank height be the 1/2, three opening 9 of whole purification tank height is 1/8 of whole purification tank height.Described discharge nozzle 11 is made up of vertical tube and the elbow being positioned at vertical tube two ends, and the height of discharge nozzle top elbow outlet meets: be not less than 1/2 of whole purification tank height, not higher than 3/4 of whole purification tank height; The internal diameter of described discharge nozzle is between 0.05m ~ 0.2m.
Gas push formula of the present invention is as follows from the specific works process stirring combination purification groove:
1. purification tank seals by outer wall 1 completely, can only be connected by feed pipe 10, discharge nozzle 11 with gas vent 14 with outside.
2, the matrix flowed into by the feed pipe 10 being in the first groove lattice 3 and the second groove lattice 4 central authorities below or sewage, enter in the first groove lattice 3 and the second groove lattice 4; The gas that substrate fermentation in first groove lattice 3 produces or aerobic aeration store at the first groove lattice 3 upper collection of sealing, cannot directly discharge; Under normal circumstances, the gas from gas outlet 14 that the matrix in the second groove lattice 4 and the 3rd groove lattice 5 produces is discharged.
Increasing 3, along with gas flow in the first groove lattice 3, the liquid level of its mesostroma can decline, and the liquid level of other position of purification tank can rise when matrix does not flow out; Along with the increase being stored into gas in the first groove lattice 3, when matrix liquid position is reduced to the bottom of U-shaped pipe 12 and declines further, due to liquid level principle of differential pressure, the matrix in U-shaped pipe 12 can be extruded instantaneously, and the gas in the first groove lattice 3 can be flow in the second groove lattice 4 and the 3rd groove lattice 5 by U-shaped pipe 12.
4, due to the transfer of gas in the first groove lattice 3, matrix liquid level wherein starts to rise, and the liquid level in other region starts to decline simultaneously, until liquid level is higher than the opening of U-shaped pipe 12 upper end in the first groove lattice 3, matrix or liquid fill U-shaped pipe 12; Whole purification tank liquid level no longer changes.In the process that gas in the first groove lattice 3 is discharged through U-shaped pipe 12, due to the guide functions of aeroscopic plate 13 pairs of Exhaust Gas, further increase the stirring action of matrix also liquid.
5, step 3 to 4 be one from mixing cycle; After U-shaped pipe 12 is full of matrix, continues stored-gas in the first groove lattice 3, enter the next cycle of stirring.Along with the circulation change of different parts liquid level in purification tank, matrix or liquid, by continuous intermittent stirring, thus ensure that the continuous operation of whole system.
In the case of necessary, air pump can be used the second gas circulation port 16 to be connected with the first gas circulation port 15, the gas produced in the second groove lattice 4 and the 3rd groove lattice 5 is back in the first groove lattice 3, stir to increase; Particularly startup stage, gas production is little, need increase gas transfer number ensure stir; Along with the improvement of purification tank mixing effect, the increase of gas yield, purification tank self can maintain stirring, no longer can carry out aerogenesis foldback.
Change frequency due to liquid level determines the effect of stirring, and when anaerobism is run, gas production becomes the key factor maintaining and stir; Thus, along with the substrate concentration of inflow or the increase of amount, gas production also can increase, and is conducive to the carrying out stirred, ensure that the present invention is applicable to the heavy-duty service of high concentration and Super matrix flow; And the problems such as the mixed effect that purification tank can not occur because of fermentation substrate excessive concentration is poor, material skewness.Thus there is the advantage that energy-conservation, efficient and shock resistance meets, ensure that the stable operation of purification tank.
